The states of Cu3/2PMo12O40,which was used as a modifier for Raney nickel and Raney cobalt, were investigated by XPS technique. It was found that valence states of Cu2＋ and Mo6＋ were greatly changed, i.e. Cu2＋ was reduced to Cu0 while Mo6＋ was partially reduced to Mo5＋ and Mo4+.These changes were due to the presence of active hydrogen adsorbed onto the surface of Raney nickel and Raney cobalt catalysts. Raney nickel contained less low oxidation state Mo than Raney cobalt, which was probably due to the different activity of adsorbed hydrogen species on the Raney nickel surface and Raney cobalt surface. The presence of Cu was beneficial to the hydrogenation of carbonyl. The existence of Mo improved the adsorption and activation of carbonyl. In another word, the presence of Cu and Mo complemented each other in the hydrogenation of carbonyl.
